FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 308,513, dated November 25, 1884. Application filed August 4, 1B `4. (No model.)

T0 @ZZ whom, t may concern.-

Be it known that I, VILLIAM inwcoiin, a citizen ofthe United States, residing at Johnsonville, in the county oi' Rensselaer and State of New York, have invented new and useful Improvements in Fire-Arms, of which the following is a speciiication.

This invention has for its object to provide a novel and efficient fire-arm having two or more barrels, two tiring-pins or nipples, and a hammer common to both firing-pins or nipples.

The invention consists in the construction and combination of devices hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 represents a sectional side view of the iirc-arm. Fig. 2 is a plan or top view of the same.l Fig. 3 is a perspective View ofthe striking-slide detached. Fig. 4 is a horizontal section of the trigger and the arm for liiting the striking-slide.

Similar letters indicate corresponding parts.

In these drawings, the letter A designates the stock. B is the breech-block. C D are the side barrels, and F is the middle barrel. These three barrels are fastened together. by any suitable means, such as usually employed for fastening together the two barrels of double-barreled guns, and they are attached to the breech-block by well-known means so that they can be tilted up to expose their breech ends for the reception of the cartridges. These parts, however, form no part of my invention, and it is therefore not necessary to give a detailed description of the same. On the sides ot' the stock are two hammers, F G. The hammer F acts upon the iiring-pin c of the side barrel, D, while the hammer G is so situated that when it comes down without meeting any obstruction it will strike the iiring-pin d of 'the side barrel, D. The outer end of the ring-pin c of the middle barrel is situated in close proximity to the firing-pin d, and it extends through the breech-block in an oblique direction, as indicated in dotted lines in Figs. l and 2.

In order to bring the firing-pin e into the range of the-hammer G, I have applied the striking-slide H. This striking-slide is placed into a recess, f, formed in the stock, and it is provided at or near the middle of its length with a knuckle, g, Figs. l and 3, which bears against the rear surface of the breech-block B. Near its lower end said slide is provided with a short arm, 7a., Fig. 3, the upper surface of which is slightly inclined, Fig. l, and exposed to the action of a spring, I, which is situated in a recess, J, in the side of the breech-block. This spring has a tendency to force the striking-slide downward, and also to throw the lower end thereof inward against the rearsurface of the breech-block. 0n this lower end is formed a sharp-edged spur, i, and if the slide is moved up to the position shown in full lines in Fig.-l the spring I throws this arm into a recess, j, formed in the rear surface of the breech-block. At the same time the head 7i: of the slide is thrown back and brought in such a postion that it is situated in the range of the hammer G, and also opposite to the outer end of the iiring-pin e of the middle barrel, E. Vhen the hammer G comes down, it strikes the head k and drives the same i`orward,so as to force the firing-pin cinward, while at the same time the slide forms a guard whereby the hammer is prevented from coming in contact with the iiringpin d of the barrel D. When the hammer G drives the head 7c of the slide H forward, the spur 'i is thrown out of gear with the recess j, and the slide, being treeto follow the action of the spring I, is depressed to the position shown in dotted lines in Fig. l, and if thehammer is cocked, the slide, having assumed this last-named position, leaves the hammer free to strike the firing-pin doi" the side barrel, D.

In order to prevent the slide following the action ofthe spring I pre1na-turely,a shoulder, Z, is formed on the rear surface ot' the breechblock,and when the hammer strikes the head of the slide, so as to drive the firing-pin cforward, said slide,being tree to follow the action of the spring I, sinks down a sui'icient distance to prevent the spur t' from entering the reccssj. If the hammer is then cocked, the head of the slide is thrown back bythe action ofthe spring I, so as to clear the shoulder Z, and then the slide'is depressed to the position shown in dotted lines in Fig. l.

For the purpose` of raising the slide to the position shown in full lines in Fig. l, I use IOO an arm, K, which swings loosely on the pivot m of the trigger L,and apin, o, secured therein, Figsl and 8, rests against the edge n of the pin of this trigger. `When the trigger is pressed forward in the directionof the arrow marked near it in Fig. l, the front end of the arm K forces the slide up until its spur t' catches in the recess j. If desired, however, the slide may be so constructed that a portion of it extends out through the bottom of the recess f in the stock, so that it can be forced up by pressing with the finger against this extension. If desired, both firing-pins d c may be placed outside ofthe range ofthe hammer, and in this case the slide H must be so constructed that the same when moved up will enable the hammer to act upon the firing-piu e, and when it is moved down it will enable the hammer to act upon the firing-pin d.

It must be remarked th at my invention can also be applied to muzzle-loaders, in which case the hammer serves to explode a percussion-cap placed upon nipples, which take the places of the firing-pins shown in the drawings.

I am aware that hammers have heretofore been provided with movable attachments to enable them to act on two diiferent firing-pins or nipples, and I do not claim as my invention a double-barreled gun in which one and the same hammer can be adjusted to act first upon the firing-pin or nipple of one, and then upon the firing-pin or nipple of the other barrel.

"What I claim as new,and desire to secure by Letters Patent, is-

1. The combination, with two barrels, a single hammer, and two tiring-pins or nipples,

of the verticallymoving slide H, having a knuckle on which it can rock, and arranged between the hammer and the iiring-pins or nipples, substantially as described. Y

2. The combination, with two barrels and two ring-pins or nipples, of the slide H, provided at or adjacent to the center of its length with a knuckle on which it can rock when struck by the hammer, said slide having a head, 7c, to act on one of the firing-pins or nipples and at the same time constitute a guard to prevent the hammer from striking the other ring-pin or nipple, substantially as described.

3. The combination, substantially as hereinbefore described, with two barrels and a single hammer, of two firing-pins or nipples, one for each barrel, the slide H, situated between the hammers and the two tiring-pins or nipples, and the arm K, actuated by the trigger L, and serving to raise the slide H.

,4. The combination, substantially as hereinbefore described, with two barrels and a single hammer, of two firing-pins or nipples, one for each barrel, the slide H, situated between the hammer and the two firing-pins or nipples, the knuckle g, on which the slide rocks, the spur t', and recess j, the spring I acting on the slide and having a tendency to depress the same, and means, substantially such as herein described, for raising the slide.

5. rIhe combination, substantially as -hereinbefore described, with two barrels andasingle hammer, of two iiring-pins or nipples, one foreach b-arrel, the slide H, situated between thehammer and the two firing-pins or nipples, the knuckle g, on which the slide rocks, the spur fi, and recess j, the spring I acting on the slide, and having a tendency to depress the same, the shoulder Z, and means, substantially such as herein described, for raising the slide.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
